Thread: The most awesomest sound in the world!!!

Drove it to the exhaust place today. He is very busy (fitting it in between jobs), and doesn't like the lack of space in the engine bay... (needs to squeeze in a 3" flex pipe and 3" mandrel system...)

So far, no problems at all with the install. Turbo is 100% and the oil stays where it is supposed to.

Don't they howl, When I cut mine off under cab and then put a stack up the back of cab with inverted Hot Dog it still has awsome Turbo whine even at tick over.But not to noisy Mine is only 2 &/2"
3" mandrel would be great. I have noticed a bit of pressure buildes up on my 2 &1/2" on full song.
Hope yours goes well when done. Tony

Sorry - forgot that I have a ricer turbo - I shd hv typd txt spk lol - f'ly sik m8

you're just kidding eh!
that whistle from the turbo is friggen bad noise.
actually a [margueritz?] deutz is a bad noise.[ansett buses - nice body though]
why do you want it to make **** loads of obnoxious noise, and perform badly?

obviously you have never heard a merlin at full noise.

Makes parts of my body twitch just thinking about that sound, Inc is right, I love the sound of my Suzi but, it's like comparing sitting on Santa's lap to a naughty lapdance with Jennifer Hawkins, they have similar content in the description but are totally different.

Try 600+hp of Chrysler 426 Hemi under load at 6000rpm through four x 3" tailpipes. Best street engine noise I was ever party to.

Or the sound from a turbo Offy pulling 1400hp, 12,500rpm, and 70" boost on the Champion Spark Plug development dyno at Long Beach. A Gurney AAR engine. I was there. You can feel and taste the sound through double filled block walls.

2 things, Champion plugs are devils semen and 70" of boost? should be PSI, your showing your age Brian

But yea, I;d rather listen to a mopar V8 any day

Jesus Dobbo you are responsible for spilling my coffee over my desk with that post...(visions in my head)

You are correct. Ahlzheimer's strikes again. It was 70psi total pressure. 55lb. of boost over atmospheric. They had the wastegate wired shut to see what they could get in terms of both boost and power. There was a mandatory preset wastegate for Indianapolis so in theory everyone ran the same boost. Of course there was a considerable amount of human ingenuity applied to this (cheating?) to get around the rules. They were doing a lot of testing of alternate ignition systems on these engines at the time. Magnetos had been found wanting at the revs and pressures involved and spikes were destroying a few engines. These were the early days of electronic ignition systems and there were a lot of odd designs and theories about, and this sort of engine performance was completely uncharted territory. These were only about 2.6 litre four cylinder engines that had to run 500 miles plus, hopefully, practice and qualifying.

One of these engines, a late one at that, was for sale two years ago, stated to be unused. US$25000. Not clear whether this was new unused, or unused after overhaul. Not really much use except as an exhibit unless you have an Indy car of the period needing an engine.
